To all 'whom it may concern:

Beit known that we, GEORGE B. KELLY and FREDERICK L. WOOD, Acitizens of the United. States, and residents of Jamaica Plain, Suffolk county, State of Massachusetts, and Worcester, in the county of Worcester and State of Massachusetts, respectively, have invented certain 'new and useful Improvements in Playing Attachments for lMusical Instruments, of which the followtracker board over which the sheet is drawn,`

The object of our invention is to provide a new and improved frame orstructure in which the shafts for the rolls, the means for adjusting the rolls lengthwise and the winding and rewmding gear are all contained in a structure as an entirety so that this .structure as an entiretycanbe placed Into and secured in the playing attachment or machine without requiring any adjustment-of parts or attaching of parts aft-er this structure asv an' entirety, has been secured in the instrument.

In the accompanying drawings, in which like letters of reference indicate like parts in all the gures:-,-Figure 1 is a ,vertical sectional view of our improved .frame and vthe winding, adjusting and motor gear mounted therein, parts being shown in elevation and Others broken away. F1g. 2 1s a side view of the same, parts being in section and others broken away and others omitted. Fig. 3 is a plan view of part of the same.

The franie is composed of two side pieces 1 and 2, united, by cross bolts 3. In the top part of the frame a horizontal shaft 4' is' mounted in bushings y5 in the `side plates 1l l and 2, one end 6 ofsaid shaftbeing forked or Otherwise shaped to receive a pin or 'projectionyon one end o f a music r'oll.- The right hand end` of this shaft is shaped asj a step 7 which bears against a step bearing 8 mounted in said bushing to move ,lengthwiseof the shaft 4 which step bearing can be adjusted by a screw 9 bearing against the outer end of the stem 10 of said step bearing, said screw being screwed through an arm 19 of a rockfshaft 11 mounted 1n curved brackets 12 projecting from the outer side of the said plate 2. The lowery shaft 13, for the ltake up roll, is also provided wlth a forked end, or equivalent structure for re ceivi'ng a projection On one end ofthe take] up roll, and th'isshaft 13 is mounted in the bushings 111, the right hand end of said shaft 13 also bearing against a step bearmg 15, movable in the bushings v141 and `having a stem 16 against the outer end of which a screw 17 rests which is screwed through the arm 18 on the lower end of the rock shaft 11. The rock shaft 11 is provided with an arm 20 the Outer end of which is connected 1 with a manipulating link 21 by means of.

which the rock shaft'can be rocked and thus y the arms 18 and 19 of this rock shaftmoved in the direction toward or from the side wall 2. 4

Vhen the arms 18 and 19. are'swungtoward the side wall 2 both shafts 4 and 13 are moved to the left, Fig. 1, but when these arms 18 and 19 are swung from the side wall 2, they permit the music rolls to be forced to the right by the springs usually provided in instruments of this kind, to press on those bearings for the rolls Opposite the bearings 6 and which springs are not shown as they form no part of the present invention, and

, the rolls exerting a pressure on the shafts 4 and 13 move them in the direction toward, a

the right, Fig. 1, as far as the stop screws 9 and 17 in the arms 18 and 19 respectively, will permit. Both shafts 4 and 13 can thus be adjusted longitudinally at'the same time.A

A cog wheel 22 is fixed on the shaft 13 and can be engaged by a pinion 23 mounted on a shaft 24 to turn with said shaft and move lengthwise On said 'shaft which shaft 24:.car-

ries a sprocket wheel 25, which is rotated by means of a sprocket chain 26 froml a suitable mo'tor. The pinion 23 is connected with a clutch 27 which, with the` pinion, canbe shifted by means of a lever :28, pivoted at 29 and the upper end of'which lever engages said clutch 27. A link BO serves for shifting thelever 28 from some other part offthe instrument. "Asprocketwlieel 31 is'.

mounted loosely on the shaft 24 andover this sprocket Wheel 3l a sprocket chain 32 passes which also passes over a sprocket wheel 33 fixed on the shaft 4. The clutch 27 is provided with a pin 40 and the 4loose sprocket wheel 31 is provided with the clutch m41. When the motor of theinstrument 1s operated the shaft 24 is constantly rotated in the same direction and when the pinion 23 is engaged with the cog wheel 22 the lower shaft 13 is rotated but the upper shaft 4 is not rotated as the sprocket 31 is loose on the shaft 24. Vith the parts engaged as shown in Fig. 1, Athe note sheet is being unwound from the roll onthe upper shaft 4 upon the roll on the lower shaft 13. When the direction of movement of the paper is to. be reversed, the clutch 2T is so shifted as to disengage vthe pinion 23 from the cog wheel 22 and as to bring the clutch pin 40 in engagement with the clutch pin 41 on the loose sprocket-wheel 3l so that the latter is rotated and .motion is transmitted by means of the sprocket chain 32 and sprocket Wheel 33 and the upper shaft 4 which is rotated in the reverse order at high speed and the sheet wound upon the music or upper roll. Itwill be seen that the two shafts 4 and 13 as well as the driving 'gear for the same and the reverse gear and the means for adjusting the shafts longitudinally are all mounted on the frame composed of the two sideplates l and 2 and the bolts 3 so that this entire mechanism as an entirety can be secured in the instruments without requiring l any further adjustment or fastening or mounting of parts.

Having described our invention what wev claim as new and desire to secure by Letters Patent is zl. A playing attachment for that class of musical instruments making use of a perforated music sheet and two rolls for Windlng and rewinding the sheet, having a frame contalning two rotative music roll shafts which are the only music roll shafts carried by the said frame and which shafts are mounted in vsaid frame, gearing for rotating 4the shafts which gearing is also mounted in the frame, which frame, with the parts contained therein, is attached as an entirety to the casing of the instrument, whereby the parts carried with the framel have no other connection with the instrument, substantiallyas set forth.

2. A playing attachment for that class of musical instruments making use of a perforated music sheet and two rolls for winding and rewinding the sheet having a frame containing two rotative music roll shafts which are the only music roll shafts supported on said frame and which are mounted in the frame, means for reversing the direction of rotation of said shafts which means are also mounted in their frame and which longitudinally,

frame with parts therein, is attached as an entirety to the casing of the instrument -whereby all parts carried by the frame have no other connection with the instrument, substantially as set forth.

3. A playing attachment for that class of musical instruments making use of a perforated music sheet, and two rolls for windy ing and rewinding the sheet, having a frame containing two rotative music 'roll shafts which are mounted in said frame and gearing for rotatin Y the shafts and means for shifting the shafts longitudinally all mounted on said frame, which frame, with the parts contained therein, is attached as an entirety to the casing of the instrument, whereby the parts are not attached individually to the casing of the instrument but are mounted in this frame only, 4substan tially as set forth.

4. A playing attachment for that class of musical instruments making use of a erforatetl music sheet and two rolls for winding and rewinding the sheet, having a frame containing two music roll shafts which are mounted in the frame and which shafts are longittulinally movable in the bearings in said frame and means for shifting the shafts .longitlulinally iu their bearings which means are also mounted in the said frame, which frame, with the parts contained-therein, is attached as an entirety to the easing of the instrument, whereby the parts are not attached individually to the casing of the instrument but are mounted in this frau'ie only,

substantially as set forth.
